MAX4397DA/SA
Audio/Video Switch for Dual SCART Connectors
______________________________________________________________________________________

The slow-switching feature allows for bidirectional, tri-
level, slow-switching input and output signals at pin
VCR_SS and TV_SS, respectively. The slow-switching
signals from the VCR set the aspect ratio or video source
of the TV screen. See the Slow Switching section.
Fast switching consists of two inputs from the encoder
and VCR, and one output to the TV to insert an on-
screen display (OSD). Fast switching is used to route
video signals from the VCR or from the encoder to the
TV. In addition, the fast-switching output can be config-
ured to a high or low voltage. Fast switching is con-
trolled through the I2C interface.
The digital block contains the 2-wire interface circuitry,
control, and status registers. The MAX4397DA/SA can
be configured through an I2C-compatible interface.
DEV_ADDR sets the I2C-compatible address.
SCART Video Switching
The MAX4397DA/SA switch video signals between an
MPEG decoder, TV SCART, and VCR SCART. The video
switch includes reconstruction filters, multiplexed video
amplifiers, and a Y/C mixer driver for an RF modulator.
See Figure 1 for the functional diagram of the video sec-
tion. While the SCART connector supports RGB, S-video,
and Composite video formats, RGB, and S-video typically
share a bidirectional set of SCART connector pins.
